1 Claim. 1

This invention relates to forms for concrete structures. In its moreparticular aspects the invention is directed to forms for definingopenings in concrete structures.

It is the chief object of the invention to provide a form for defining awindow or door opening in a concrete structure, which furnishesefficient hinge mounts for the subsequent mounting of door or windowhinges.

Still further more specific objects and corresponding advantages of theinvention will become apparent from the following description of apresently preferred embodiment, for which purpose I shall refer to theaccompanying drawings, in which:

Fig. 1 is a horizontal section taken through the forms at a windowopening;

Fig. 2 is a view taken on line 2-2 of Fig. 1;

Fig. 3 is a top plan view of one of the hinge mounts;

Fig. 4 is a front view of the mount of Fig. 3;

Fig. 5 is a section taken on line 55 of Fig. 4;

Fig. 6 is a fragmentary view taken on line 65 of Fig. 2; and

Fig. 7 is a fragmentary section taken on line 'l'! of Fig. 1.

In the drawings the numerals 5 and 6 denote a pair of spaced parallelform plates for forming a concrete wall, the poured concretetherebetween being denoted by the reference letter C. The form sheets 5and 6 form no part of the present invention except as support means forthe window form, and no claim is here made to them per se.

To form, for instance, a window opening H] in the concrete wall Iprovide side plates l5 and top and bottom plates l4 and Ma, the sideplates being comprised of lengths of metal formed into the crosssectional shape best indicated in Fig. 2 and having their abutting endedges oppositely beveled as shown at l6 (Fig. 2). Each of the lengthsgoing to make up a side plate has side flanges |5a provided with screwholes I! to threadedly receive screws 20 by which the lengths areattached to the form plates 5 and 6. To further secure each pair ofadjacent lengths together and in proper alignment I provide on eachlength, adjacent its beveled edge portion l6, a U-shaped bracket 24 eachproviding a socket to pass a retaining pin 25. The sockets as well asthe retaining pins 25 are wedge-shaped as best shown in Fig. 6, and eachbracket has side flanges 240. by which it is attached, as by welding, toits carrying length of form plate.

Each of the hinge mounts, generally denoted by the numeral 30, consistsof a metal frame having a front or outer wall 3| presenting a U-shapedmedial portion 32, end walls 33 and a back wall 34. Medially between theend walls, the front and back walls are additionally reinforced or heldin spaced relationship by a cross member 36 which may be welded at itsends to the front and black walls and has a threaded opening 38registering with an opening 39 in the front Wall for the reception ofhinge screws not shown. Threaded holes 40 are also provided through thefront and end walls to receive attaching screws 4!, 42, the threadedholes in the end walls being adapted to receive screw 42 by which thehinge mounts are temporarily secured to the form plates 5 and 6, and theholes in the front wall being adapted to receive attaching screws 4! bywhich the hinge mounts are temporarily secured to the window formplates.

Top end plate H may consist merely of a flat metal plate, althoughbottom plate Ila consists of a flat plate having a central, rectangularopening 50 Figs. 1 and 7). A cover plate 53 having relatively thin endportions 54 covers the opening, said ends being secured to plate Ma byscrews 55 which pass through openings in plate 53 and thread intoopenings 56 in plate I do. Concrete walls are usually poured from thetop so that sometimes it does not form properly at the bottoms of windowopenings and the like. The form construction which I have shown permitsof removing the plate 53, after the forms 5 and 6 have been removed, andthe pouring of additional concrete mixture through the opening 50. I

In assembling the form structure, the hinge mounts are first secured tothe appropriate lengths of the window form and then the window form isassembled and secured to one of the form plates 5 or 6, by the screws20, the hinge mounts being additionally secured to the said form plate 5or 6 by the screws 42. Then the other form plate 5 or 6 is applied andlikewise attached to the Window form and to the hinge mounts, afterwhich the wet concrete mix C is poured and allowed to set.

After the concrete has set, the form plates 5 and 6 and the window forml5 are removed, being detached from the hinge mounts 30 so that thelatter remain as permanent parts of the building structure and inposition to have hinges mounted upon them. The front wall of each hingemount is, of course, flush with the surface of the window.

Since the hinge mounts 30 are open at their tops and bottoms, the pouredconcrete may enter the space between the walls, which concrete becomesan integral part of the wall structure and confines the back wall 34 sothat it is impossible for the hinge mount to escape or become loose.

While, in the foregoing, I have resorted to considerable detail ofstructure and association of parts in describing a particular example ofmy invention, I wish it to be understood that I have done so merely tomake my invention understood and that I do not limit my invention tosuch deback and end Walls and being open at its top and bottom toreceive concrete, and a medial transverse reinforcing member secured. atits r'espective ends to the front and back walls and presenting athreaded hole in its front end, said MIYOJI OKAZAKI.
